D. Vitamin A promotes maintenance of epithelial tissue | D | Vitamin A promotes maintenance of epithelial tissue | Alright, let's tackle this multiple-choice question about Vitamin A. I need to figure out which statement is true. Let me consider each option one by one.
First, option A says Vitamin A is necessary for hearing but not for vision. Hmm, from what I remember, Vitamin A is actually crucial for vision, especially for the ... | The correct answer is **D. Vitamin A promotes maintenance of epithelial tissue**.
**Explanation:**
- **Option A** is false because Vitamin A is essential for vision (e.g., rhodopsin synthesis in the retina) but not directly linked to hearing.
